Description

I dont know if this is supposed to work or not, but it would be nice if
MethodUtils.getAccessibleMethod correctly detected accessible enum methods. I
am in the most recent production beanutils.jar (1.7.0).

I have an enum like this in its own file:

public enum DataEditDataType {

/** string data type */
STRING {
@Override
public String getValueName()

{ return "string"; }

}, ...

Then I am getting the property descriptor ok

PropertyDescriptor propertyDescriptor = PropertyUtils.getPropertyDescriptor
(DataEditDataType.STRING, "valueName");

Then the method is fine

Method method = propertyDescriptor.getReadMethod();

But then it is seen as not accessible

Method method = MethodUtils.getAccessibleMethod(method);

Which return null

The problem is line 415 of MethodUtils

// If the declaring class is public, we are done
Class clazz = method.getDeclaringClass();
if (Modifier.isPublic(clazz.getModifiers()))

{ return (method); }

For some reason, Modifer.isPrivate(clazz.getModifiers()) returns true (since
STRING is a subclass of the DataEditDataType enum. but this is an enum
(DataEditDataType) which is publicly available??? There could be a line here
to see if it is an enum, then if the superclass is public in which case it is
ok? Something like this

if (Enum.class.isAssignableFrom(clazz) && Modifier.isPublic(clazz.getSuperclass
().getModifiers()) {
return method;
}

That would work for me, but not sure if it would work in all cases or break
something else or if there is another workaround I can do for my enum code.

Thanks!
